DDOS is the most prominent security threat the internet network facing now. Among all DDOS methods, reflective DDOS is most popular and powerful attack due to low cost, low threshold and excellent effort. Meanwhile, the real reflective DDOS attack leads to more and more powerful network flow. During our research, we found a new way to exploit a specific UPD protocol which widely used in public network and obviously gains high multi reflective network flow. The multiple can reach at 50000 which is the highest known. In this case, our researcher can exploit a 2TB/s DDOS attack only via a family network. That also means we could make most network paralyzed in a simple way.
